How to set a part of arguments from a list in Emacs Lisp?

Question

I want to set PROGRAM-ARGS of start-process from a list.

Like,

(start-process process-name "*foobar*" process-path (append some-args (list (concat "the" "other" "arg"))))

But this makes error that "... is not string", because start-process accepts only string arguments.

How can I solve this?

What's so hard about showing the real arguments to start-process, instead of foobar and some-args and "the" "other" "arg"? — C. K. Young

You want either apply or sometimes funcall. In this particular case I would go with apply but you need to be familiar with them both.

(apply #'start-process process-name "*foobar*" process-path
       some-args other-args-as-a-list)
